Description

[Technical Field]

[0001] The present invention relates to a helmet, and more particularly to a helmet equipped with a hammock inside the shell. [Background technology]

[0002] Conventionally, in a helmet having a shell and a hammock provided inside the shell, a technology is known in which an impact absorbing member is provided instead of an impact absorbing liner made of polystyrene foam to improve breathability and heat dissipation (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-66835 Summary of the Invention [Problem to be solved by the invention]

[0004] In the helmet described in the aforementioned patent document, the impact absorbing member (impact absorber) is provided on a protective pad, which is located on the outside of a hammock attached to the inside of the helmet body. Therefore, the impact absorbing member cannot be attached, detached, or replaced while the hammock is attached to the helmet. In other words, if the impact absorbing member becomes dirty or damaged, it is necessary to first remove the hammock and then remove the protective pad, which is a heavy workload for the user.

[0005] Furthermore, in the helmets described in the aforementioned patent documents, the impact absorbing members are integral with the protective pads, so they cannot be attached, detached, or replaced individually. In other words, if one impact absorbing member becomes dirty or damaged, the entire protective pad must be removed to replace the impact absorbing member, which places a heavy burden on the user.

[0006] The present invention was made in consideration of the above-mentioned circumstances, and the problem that the present invention aims to solve is to provide a helmet that can reduce the workload of the user by allowing the impact absorbing member to be attached directly to the cap body without using a hammock or other member. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the present invention provides the following helmet.

[0008] (1) A helmet comprising a cap body and a hammock attached to the inside of the cap body, the hammock having a plurality of linking parts formed radially, and the tip parts of the linking parts attached to the cap body, a plurality of shock absorbing members that partially cover the inner peripheral surface are attached between the linking parts on the inner peripheral surface of the cap body, engaging protrusions are formed on the inner peripheral surface of the cap body, and engaged holes are formed in the shock absorbing members, and the engaging protrusions are engaged / disengaged with the engaged holes, making the shock absorbing members detachable from the inner peripheral surface of the cap body, When the engaging projection engages with the engaged hole, the impact absorbing member is elastically deformed along the inner circumferential surface of the cap body, so that the outer surface of the impact absorbing member is disposed along the inner circumferential surface, A helmet wherein, in a bottom view of the helmet body, at least a portion of an inner surface of the impact absorbing member is positioned so as to protrude further inward than the tip end of the connecting portion of the helmet body. [Effects of the Invention]

[0009] According to the helmet of the present invention, the impact absorbing member can be attached directly to the helmet body without using a hammock or other member, thereby reducing the workload of the user. [Brief explanation of the drawings]

[Figure 3]FIG. 2 is a bottom view showing the helmet according to the embodiment. [Figure 4] FIG. [Figure 5] FIG. 4 is a perspective view showing the mounting configuration of the impact absorbing member. [Figure 6] 1A and 1B are an inner perspective view and an outer perspective view, respectively, of the impact absorbing member. DETAILED DESCRIPTION OF THE INVENTION

[0011] Next, the schematic configuration of a helmet 1 according to one embodiment of the present invention will be described using Figures 1 to 6. In this embodiment, the right side in Figures 1 and 2 is the front of the helmet 1, and the front side in the direction of the paper in Figures 1 and 2 is the right side of the helmet 1. That is, in this embodiment, the direction as seen by the user of the helmet 1 is defined as the direction in the helmet 1.

[0012] As shown in Fig. 1, a helmet 1 according to this embodiment has a hammock 3, a headband 4, and a plurality of shock absorbing members 5, each made of a soft synthetic resin or the like, detachably attached to an inner peripheral surface 2P of a cap body 2 made of a hard material such as synthetic resin. For the sake of convenience in explanation, the headband 4 is not shown in the drawings other than Fig. 1 in this embodiment.

[0013] The hammock 3 is a member that protects the user's head by forming a gap between the inner peripheral surface 2P of the cap body 2 and the user's head. As shown in FIG. 3, the hammock 3 has an annular portion 30 formed in a circular ring shape at its central portion (the portion that abuts against the top of the user's head), and eight linking portions 31 formed radially extending from the annular portion 30. A linking hole 31a is opened at the tip of each linking portion 31. The linking hole 31a of each linking portion 31 engages with a locking portion 21 (see FIG. 4) provided on the inner peripheral surface 2P of the cap body 2 so as to protrude inward, thereby fixing the hammock 3 to the inside of the cap body 2. In this way, the hammock 3 is attached to the cap body 2 via the multiple linking portions 31.

[0014] 2 and 3, of the eight linking portions 31, four linking portions 31 extending toward both the left and right sides are formed with band support portions 32. Specifically, of the four linking portions 31 extending toward both the left and right sides, band support portions 32 are formed at the front of the two front linking portions 31 and at the rear of the two rear linking portions 31. Two support holes 32a are formed in each of the band support portions 32.

[0015] A headband 4 is connected to the band support part 32. The headband 4 includes a front wrapping part 41 that is wrapped around the forehead of the user of the helmet 1, and a rear wrapping part 42 that is wrapped around the back of the head.

[0016] The front winding part 41 is provided with a supported part on which a support claw (not shown) is formed. The headband 4 is supported by the hammock 3 by engaging the support claw of this supported part with the support hole 32a of the band support part 32. A connecting part 46 is formed at the rear of the front winding part 41, and extends downward when the helmet 1 is in use. A locking claw 46b is formed at the lower end 46a of the connecting part 46.

[0017] The rear winding portion 42 is configured by combining a first adjustment portion 43 on the right side and a second adjustment portion (not shown) on the left side. The first adjustment portion 43 and the second adjustment portion are relatively displaceable, and their relative positions are fixed by a lock portion 45. That is, the length of the rear winding portion 42 is adjustable by changing the relative positions of the first adjustment portion 43 and the second adjustment portion. The first adjustment portion 43 is formed with an adjustment groove portion 43b for fixing its relative position with the second adjustment portion.

[0018] The front end portion of the rear winding portion 42 (the front end portion 43a of the first adjustment portion 43 and the front end portion of the second adjustment portion) is rotatably connected to the lower end portion of the connecting portion 46. Specifically, a locking hole 43c is opened in the front end portion 43a, and the locking claw 46b of the connecting portion 46 is inserted into the locking hole 43c, whereby the rear winding portion 42 is rotatably connected to the connecting portion 46.

[0019] 2, on the inner peripheral surface 2P of the cap body 2, a plurality of (four in this embodiment) shock absorbing members 5 that partially cover the inner peripheral surface 2P are attached between the connecting portions 31 of the hammock 3. The shock absorbing members 5 are made of a material such as polyethylene, polypropylene, polylactic acid, polyamide, elastomer, etc.

[0020] 3, in this embodiment, four impact absorbing members 5 are attached to the inner circumferential surface 2P of the helmet body 2: a front member 5F attached to the forehead, a rear member 5B attached to the back of the head, a right member 5R attached to the right side of the head, and a left member 5L attached to the left side of the head. In the helmet 1 according to this embodiment, by providing the impact absorbing members 5 at four locations (front, back, left, and right) on the inner circumferential surface 2P of the helmet body 2 as described above, it is possible to effectively absorb impact when the user falls. Note that each impact absorbing member 5 is formed to have the same shape, so the following description will only cover one impact absorbing member 5.

[0021] 4 and 5, in the helmet 1 according to this embodiment, the cap body 2 is formed with engaging portions 22 that protrude inward from the inner peripheral surface 2P as joining portions for joining the impact absorbing member 5 to the inner peripheral surface 2P. The engaging portions 22 are formed in four locations on the cap body 2: the forehead, the back of the head, and both the left and right sides of the head.

[0022] 6(a) and 6(b), the shock absorbing member 5 is integrally formed of a planar base surface portion 51 and a plurality of (seven in this embodiment) protruding surface portions 52 protruding from the base surface portion 51. In the shock absorbing member 5 according to this embodiment, three protruding surface portions 52 are formed on the upper side, three on the lower side, and one in the center in the vertical direction. In addition, in this embodiment, the surface of the base surface portion 51 opposite the surface from which the protruding surface portions 52 protrude is formed as an inner surface 51R. In this embodiment, by integrally forming each shock absorbing member 5, the manufacturing process is simplified and costs are reduced compared to a configuration in which multiple components are assembled.

[0023] The impact absorbing member 5 is attached by a protruding surface portion 52 formed in the center in the up-down direction abutting against the inner circumferential surface 2P of the helmet body 2. Specifically, the protruding surface portion 52 is formed with an engaged portion 53 that can engage with the engaging portion 22. The impact absorbing member 5 is attached to the helmet body 2 by engaging the engaged portion 53 with the engaging portion 22, as shown by the dashed-dotted arrow in FIG. 5 . This causes the inner surface 51R of the impact absorbing member 5 to face the user's head. This allows the area of ​​the impact absorbing member 5 that abuts against the user's head to be relatively large, thereby improving the safety of the user when an impact is applied to the helmet 1. Note that it is also possible to form an engaged portion on the inner circumferential surface 2P of the helmet body 2 and form an engaging portion on the impact absorbing member 5.

[0024] As described above, in the helmet 1 according to this embodiment, the impact absorbing member 5 can be attached directly to the cap body 2 without using other members such as the hammock 3. This allows the impact absorbing member 5 to be attached to the cap body 2 regardless of how the hammock 3 and other members are attached to the cap body 2.

[0025] Moreover, the impact absorbing member 5 according to this embodiment can be attached to and detached from the inner circumferential surface 2P of the cap body 2 by engaging / disengaging the engaging portion 22 and the engaged portion 53. By making the impact absorbing member 5 attachable to and detachable from the inner circumferential surface 2P of the cap body 2 in this way, it becomes possible to easily clean and repair the impact absorbing member 5.

[0026] Furthermore, in the helmet 1 according to this embodiment, the impact absorbing members 5 are individually attached to the cap body 2, making it easy to attach, detach, or replace each impact absorbing member 5. In other words, if one impact absorbing member 5 becomes dirty or damaged, it is possible to replace just that impact absorbing member 5, thereby reducing the workload on the user.

[0027] Furthermore, in the helmet 1 according to this embodiment, the impact absorbing members 5 are attached to the shell 2, which is a member that is farther from the user's head than the hammock 3. This makes it possible to ensure a ventilation space between the head and the inner peripheral surface 2P of the shell 2. In other words, compared to a configuration in which the impact absorbing members 5 are provided on the hammock 3, the impact absorbing members 5 can be placed farther from the head, allowing air to circulate near the head and increasing the user's sense of coolness.

[0028] 2 and 3, the shock absorbing member 5 is detachable from the inner peripheral surface 2P by being inserted between the connecting portions 31 with the hammock 3 attached to the cap body 2. Therefore, even if the shock absorbing member 5 becomes dirty or damaged and needs to be replaced, there is no need to remove the hammock 3, which reduces the workload on the user.

[0029] Note that, in addition to the configuration of this embodiment, other configurations can be used to fix the impact absorbing member 5 to the cap body 2, such as welding, screwing, integral molding by two-color molding, etc. Note that from the viewpoint that the cap body 2 and the impact absorbing member 5 can be integrally formed by molding, and that attachment and detachment to and from the cap body 2 can be made easy (reducing the number of steps required to assemble the helmet 1), it is desirable to use a locking structure like this embodiment.

[0030] In this embodiment, for reasons of breathability and cost, the impact absorbing members 5 are formed partially on the inner peripheral surface 2P of the cap body 2. As in this embodiment, it is desirable that a plurality of impact absorbing members 5 (four in this embodiment) are formed in a planar shape on the inner peripheral surface 2P of the cap body 2. In this case, it is desirable to form the inner surface 51R of the impact absorbing members 5 with an area in the range of 30 to 50 square cm in order to fill in the gaps in the hammocks 3 that absorb impact.

[0031] When the user of the helmet 1 receives an impact or the like from above while wearing the helmet 1, an upward frictional force is applied from the user's head to the impact absorbing member 5. For this reason, in this embodiment, as shown by arrow M in Fig. 2, the impact absorbing member 5 is displaced (upward) toward the top of the head on the inner circumferential surface 2P of the helmet body 2, so that the engaging portion 22 engages with the engaged portion 53. As a result, when the user of the helmet 1 receives an impact or the like from above, the frictional force applied to the impact absorbing member 5 makes it difficult for the impact absorbing member 5 to come off.

[0032] As shown in Figures 6(a) and 6(b), a plurality of holes are opened in the base surface portion 51 of the impact absorbing member 5. The protruding surface portions 52 are formed in arch portions that straddle the respective holes. Specifically, the three protruding surface portions 52 formed in the upper portion of the impact absorbing member 5 and the three protruding surface portions 52 formed in the lower portion of the impact absorbing member 5 straddle the holes in the left-right direction, in other words, form arch portions that penetrate in the up-down direction. Furthermore, the one protruding surface portion 52 formed in the center of the impact absorbing member 5 in the up-down direction straddles the hole in the up-down direction, in other words, form an arch portion that penetrates in the left-right direction.

[0033] In this way, the shock absorbing member 5 according to this embodiment is formed with arch portions that straddle the holes in a mixture of different directions, thereby ensuring the strength of the shock absorbing member 5. Furthermore, by forming many openings on the surface of the shock absorbing member 5, the breathability of the shock absorbing member 5 can be further improved, thereby further improving the feeling of coolness for the user.

[0034] The shape of the shock absorbing member 5 is not limited to the arch shape of this embodiment, but may also be a dome shape, a honeycomb shape, a plate shape, or the like, which can provide high energy absorption efficiency. The shock absorbing member 5 may also be shaped like a spring member that absorbs shock by bending and deforming. The shock absorbing member 5 may also be formed from a soft material such as an elastomer or rubber material to achieve shock absorption. [Explanation of symbols]
